Active matrix-based display technologies of the future require semiconductor materials with a higher performance than a-Si, better upscalability than LTPS and easier processing than IGZO. Evonik offers a series of liquid formulations called iXsenic S for the solution-based processing of metal oxide semiconductor layers. These formulations are currently optimized for spin and slot-die coating although any solution-based process is feasible.
Our products are designed to drive backplane unit for LCDs or OLED displays. Product samples are available as “ready-to-use” formulations in a litre scale and are bottled under cleanroom conditions.
In spite of such good results, we are constantly working on improving our materials and processes with the focus on the following topics:
Developing direct patternable formulations
Decreasing process temperature and time
Increasing electrical performance and stability
